Touch latch (6), after unlocking apparatus (7) postpones the preset time, tube head strains stay cord (5), stay cord (5) bounces back in the exceptionally straight pin-and-hole that backing pin (2) retracts hook, gear sheet (3) loses constraint, sway under the effect of gear leaf spring (4), (1) will be linked up with and open.
The installation mode of described backing pin (2) on hook (1) is for being telescopic fashion or rotated versions.
Described backing pin (2) all can indentation hook (1) under the pulling force effect of stay cord (5) and under the compressing of external force.
Described gear leaf spring (4) is torsion spring or leaf spring.
Described stay cord (5) is cable wire or rope.
Described latch (6) is flexible latch or rigidity latch.
The shake-up mode of described latch (6) is manual type or naturally touches when hook (1) rotates around shell (8) after hanging weight and landing.
It is an advantage of the invention that:
Compared with departing from manual type, having easy to use, separation in time, Working environment is by advantages such as air-drop weight size and position limit, cost of labor are low;
Explode compared with bolt with combustion-explosion type, have that cost is low, simple and compact for structure, easy to use, stable performance, immunity from interference are strong, without potential safety hazard, can the advantage such as Reusability, life-span length.

Embodiment
Embodiment 1: below the present invention is described in further details. As shown in Figure 1, 2,
A kind of mechanical type hook separation device, wherein:
Link up with 1 head and it is provided with pin-and-hole, elastic backing pin 2 head stretches out from pin-and-hole, link up with 1 root and shell 8 hinged, hook 1 can rotate around shell 8, gear sheet 3 head is blocked by backing pin 2 head, gear sheet 3 root and hook 1 root pin joint, and keep off sheet 3 root near being provided with gear leaf spring 4 between the position at middle part and hook 1 root; Unlocking apparatus 7 is arranged on shell 8, and the tube head of unlocking apparatus 7 is connected with one end of stay cord 5, and stay cord 5 is connected through hook 1 with backing pin 2 root, and the lining of unlocking apparatus 7 is provided with latch 6;
Touching latch 6, after unlocking apparatus 7 postpones the preset time, tube head strains stay cord 5, and stay cord 5 bounces back in the exceptionally straight pin-and-hole that backing pin 2 retracts hook, and gear sheet 3 loses constraint, sways, opened by hook 1 under the effect of gear leaf spring 4.
The installation mode of described backing pin 2 on hook 1 is for being telescopic fashion.
Described backing pin 2 all can indentation hook 1 under the pulling force effect of stay cord 5 and under the compressing of external force (gear sheet 3 ecto-entad rotates).
